All the packages provided on getdeb must be built from debian sources and can only be provided by authorized contributors. In order to be able to test the packages before distributing them in the main repository, we have setup a "testing" repository, all packages must go into this repository before being published.
Despite our best effort by building and testing packages on our systems prior to upload, there maybe some unexpected problems, the -testing repository SHOULD NOT be used on production systems, it is mostly interesting to those which plan to give some feedback about the package status so that we promote it or fix it later.
To configure the repository on your system, from the terminal type:
echo "deb http://archive.getdeb.net/ubuntu jaunty-getdeb-testing apps games" | sudo tee /etc/apt/sources.list.d/getdeb-testing.list wget -O- http://archive.getdeb.net/getdeb-archive.key | sudo apt-key add -
